摘要
JK13井区是牛地气田最早投入开发的井区之一,目前已进入递减期,因此对该井区开展了井间加密的可行性分析。根据产量劈分模型和试井的压降漏斗分析方法,分析了前期已部署加密井加密的合理性,为后期部署加密井作指导;利用流动物质平衡法计算了该井区盒3、盒2、山1三主力层位目前的地层压力,了解目前地层压力分布情况;运用试井解释结果,分析了目前井网井距的合理性。研究结果表明,目标区井网整体部署较为合理,局部位置存在井间加密的可行性。
Well JK13 is one of the earliest wells in the Daniudi gas field and has now entered a descending period.Therefore,feasibility analysis of the cross-well between the wells is carried out.According to the production splitting model and the pressure drop funnel analysis method of well test,the rationality of encrypting the deployed well in the early stage is analyzed,which guides the later deployment of the well.The current formation pressure of the three main horizons in the well block is calculated by the method of fluid mass balance,and the current distribution of formation pressure.Using well test interpretation results,the rationality of current well spacing is analyzed.The research results show that the overall layout of the well pattern in the target area is reasonable and the cross-hole encryption is feasible in some locations.
